Friends: Where could I find the specs for the repeated messages filter in Listserv? Alternatively, could anyone provide an answer to these: When a message arrives at the list server, how many lines are checked at the beginning and/or at the end in order to let it through? Also, if I send a message again, when will Listserv consider it "new"? In othe words, when will it "forget" the previous version of an old message? Finally, if two messages have the same text but different subjects, will it check the contents anyway, or will it assume it is a new message?
